Specification of Letters Patent.

Patented March 1'7, 1908.

Application filed June 28, 1906. Serial No. 323,822.

To all whom it may concern:

Be it known that 1, JOHN lLLrNowon'rn, a citizen of the United States, residing at Newark, county of Essex, and State of New Jersey, have invented new and useful Improvements in Ingot-Con'rpressing Apparatus, of which the following is a specification.

This invention relates to the art of casting ingots as illustrated by my prior patents No. 594,157 of November 23, 1897, No. 644,918 of March 6, 1000, and No. 810,654 of January 23, 1906, and the objects of the present improvements are to enable theingot to be compressed directly, or without the intervention of the mold, for the removal or prevention of piping; to thus eliminate the strain and Wear upon the molds, as well as their liability to breakage under the severe pressure; to thus reduce expense; to enable either a sec.- tional or solid mold to be employed in connection with compression of the ingots; to locate the pressure where it will be most effective upon the sides of the i'ngot and thus economize force or power; to secure more effective pressure of the ingot and thus a better product; to obtain a quick release of the ingot after it has been compressed, and to secure other advantages and results which may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each. of the several figures, Figure l is a plan of a machine of my improved construction showing an ingot just entering the same; Fig. 2 is another plan similar to Fig. 1 except that it shows the ingot just about to be released from compression; Fig. 3 is a vertical section on line at, Fig. 1, and showing a compressed ingot just discharged; Fig. 4 is a detail plan of an ingot bein compressed by rams with rounded faces, and Fig. 5 is a side elevation of one of such rams.

It will be understood that heretofore in the art, as shown by my prior patents, the ingot has been compressed while still in its mold, and to this end the mold has been made sectional with filler pieces to be removed, or wedges'to be inserted in a solid mold, and so both mold and ingot have received the pressure to ether. As a result the molds have been lia ble to be broken or damaged, and inasmuch as the construction of said molds involves much labor and expense, their breakage is a considerable item. By my present improved method herein set forth, the in 0t 18 removed from its mold while yet partia lly soft and subjected to pressure directly and alone, without the mold.

In carrying out this method, after the molten metal has been poured in any ordinary and well-known manner, the ingot is allowed to cool slightly so as to solidify at its outer portions next the mold and is then removed from said mold either by its natural shrinkage or by the use of a stripper or in any other suitable manner. After this removal, and while the central portion of the ingot is still soft, it is subjected to compression by any suitable means such as one of those which will be hereinafter described. Preferably this pressure is applied to the lateral sides of the ingot and initially at a point directly opposite the point of greatest piping or shrinkage.

Coming now to a description of the apparatus employed in carrying out my invention, Figs. 1 to 5 inclusive show a construction which is preferred for large ingots, or such as weigh several tons. In these drawings, 2 indicates a suitable base or bed-plate for the machine and upon which its various parts are arranged. Extending upward from this bed-plate 2 are walls or plates 3, 4, preferably at right angles to each other and it is in the corner between the bed-plate 2 and upright plates 3, 4, that the ingot is compressed. To effect such pressure a pair of vertically arranged hydraulic cylinders 5 are arranged opposite the upright plate 3, their pistons carrying at the end next said plate 3, a vertically disposed ram 6; this ram by the operation of the hydraulic cylinders moves toward the compression plate 3 along a line parallel to the face of the com ression plate 4 and adjacent thereto. Simi arly hydraulic cylinders 7 are arranged opposite the compression plate 4 and carry a ram 8 which moves parallel to the compression plate 3 to press against the compression plate l. Tie rods 9, 9, bind the frame 10 of the cylinders 5 to the compression plate 3 and other rods 11, 11, serve in a similar capacity with reference to the frame 12 of the cylinder 7 and the compression plate 4,. so that great rigidity is attained.

The ingot is brought to the compression machine by means of a stripper 13, adjustably mounted in the slideavay 14, of a cranearm 15, adapted to swing upon a vertical wherever desired.

pivot 16, so that the bed-plate 2 to push the ingot 19 from the compression plate 3,

where it is delivered by the, stripper, into position in front of the ram 6, as shown in dotted lines at 20 in Fig. 1. The ram 6 is then moved forward to bring the ingot against and then the ram 8 advanced so that the parts of the machine appear in the positions shown in Fig. 2. Compression of the ingot then occurs, and obviously the walls of the rams and compressing plates may be inclined or otherwise shaped to correspond to the ingot. Furthermore, since the piping of an ingot occurs increasingly toward its top, the faces of both the rams and compression plates are wedgelike from the top downward, and also round all as shown in Figs. 4 and 5, because the piping is only at the center of the ingot. In said Figs. 4 and 5, 21 indicates an ingot being compressed between such rounded faces 22 of-compression plates 23, and 24, 25 of rams 26, 27. After compression, the ingot should be released as quickly as possible in order to pass onward to the'furnace and allow another one to take its place, without loss of time and heat, and for this purpose I have provided in the bed-plate 2 an opening 28 through which the ingot may fall as soon as the rams are slackened, and be directed by a guide 29 onto conveyer rollers 30 adapted to transport it wherever desired, the reference numeral 31 in Fig. 3, indicating an ingot being thus-discharged from the machine. To support the ingot while being compressed, the ram 6, has a foot or ledge 32 adapted to slide in the opening 28, and an extension 33 thereof, flush with the bed-plate 2, to carry the ingot, as shown in Fig. 3 more particularly.

Obviously neither the stripper nor a solid mold is essential to my invention, but a sectional or divided mold could be employed, the only new feature being to remove the ingot from the mold and thus secure a more eflective pressure.

The term ram is used herein to designate any suitable pressure exerting means, whether operated by hydraulic cylinders or otherwise.

Having thus described the invention, what I claim is 1. Ingot-compressing apparatus comprising in combination ingot supporting and holding means forming a backing for one end and certain of the. sides of an ingot, and pressure-exerting means adapted to act on the remaining side portions of an ingot so held.
